Visual analysis of research progress on fibrobronchial bronchoalveolar lavage in China from 2003 to 2023
Objective To analyze the current research status of fibrobronchial bronchoalveolar lavage(BAL)in China,explore the development context and research hotspots.Methods This study was conducted from 2003 to 2023 by searching the Chinese literatures on fibrobronchial BAL collected from China National Knowledge Infrastructure,Wanfang Data Knowledge Service Platform,VIP and SinoMed,and extracting the information of keywords,authors,institutions and publication time of the literatures.Co-Occurrencel4.9,VOSviewer 1.6.19 and Microsoft Excel 2021 were applied to carry out data cleaning,data statistics and graph rendering,and visualized the research hotspots and trends of fibrobronchial BAL.Results A total of 4219 literatures meeting the requirements were included.The largest number of articles will be 438 in 2021.There were 522 core authors with more than 3 published papers.The institutions and journals with the largest number of publications were Hebei Children's Hospital with 26 articles and Journal of Clinical Pulmonary Medicine with 154 articles respectively.The research hotspots mainly include pneumonia,pulmonary infections,clinical efficacy,bronchoalveolar lavage fluid,bronchiectasis,and mechanical ventilation.Conclusion Fibrobronchial BAL is widely used in the diagnosis and treatment of respiratory diseases in China.In the future,it is necessary to strengthen the cooperation among researchers,deepen the theoretical basis,improve the clinical application system,and promote the further development of respiratory department in China.
